CETI now to be part of some major European projects

Eric DEVAUX, University Professor and Scientific Director of CETI

"We are already preparing a detailed action plan with our partners in the academic and industrial worlds, inside and outside of France, regarding our role in the Horizon 2020 programme, which is to be based on four main themes:

Valorization of biosourced polymers to make textiles (both technical and clothing) and recycling of textiles materials,

"Barrier" materials (filtration, acoustics, thermics, medical),

Functional nanomaterials (smart textiles, nanofibres, etc.),

Composites and complex structures

Since January 2013, we have hosted and assisted 3 masters research students:

Selven Rungiah, on the impact of spunbond process parameters on the functional characteristics of nonwovens.

Irène Harlé, on the development of bicomponent fibres through the use of phase changing materials offering improved comfort through controlled temperatures

CLARIFIL is the second collaborative project financed that uses CETI's spunlaid nonwoven equipment.

The drinks industry, like a great number of other industries (chemicals, pharmaceuticals, food, water and waste water treatment) uses several filtration processes that generally involve a pre-coat filter comprising a layer of particles called filtration additives. The most common of these additives are diatomite, perlite and cellusose products which have been used for over 80 years. The crystalline structure of diatomites, combined with their powder form, generates ecotoxicological risks when used. Regeneration of these materials is not particularly efficient as their particle size and permeability are modified, making them impossible to reuse. Their treatment, recovery and disposal are issues that are becoming increasingly problematical.The final filtration of liquids in many applications is increasingly performed with microfiltration or ultrafiltration membranes. The low porosity of these membranes however lowers the output of industrial filtration plant. Solutions for increasing the flow rate are being sought in order to reduce the number of cleaning cycles as well as the size of the plant. The current development of sub-micronic filaments using various techniques is opening up new possibilities for the filtration of liquids. CLARIFIL has an eco-innovatory approach to the development of alternative solutions to conventional filtration media and microfiltration membranes in the form of biosourced materials and combined nonwoven fibrous media offering over 60% porosity with submiconic filaments.CLARIFIL thus aims to develop solutions to replace diatomites and microfiltration membranes in order to offer filtration systems that are more sustainable (both economically and ecologically):

Replace diatoms with biosourced materials

Validate the implementation of new fibrous media

Develop liquid filters that are sustainable (in terms of their efficiency and service life)

Validate the overall design of the filter prototype in service

In the medium term (3 to 7 years), CLARIFIL's technology will be extended to other applications in the beverages market, such as beer, orange juice, soft drinks, etc.And in the long term, it aims to be used in water treatment by increasing its filtering capacity by over 50%. This market is considered by the various partners to be worth 2 billion Euro and offers sales prospects of around 100 million Euro spread over several years.

UP-tex / CETI conference at BATIMAT 2013, "The role of textiles in the construction industry, how to meet the challenge with CETI"

Discover all the solutions offered by CETI, the European Centre for Innovative Textiles, and competitive cluster UP-tex!A comprehensive response to the needs of the housing market.

Textiles are the 5th most used material in construction, after concrete, steel, wood and glass, and the choice of materials is fundamental in the design and renovation of sustainable and economic housing. It is certain that textiles are the perfect answer to the question of sustainability in tomorrow's housing. Cluster UP-tex and CETI will be identifying the areas in which textiles are being developed for the construction industry, and the potential solutions offered by CETI's facilities, at the conference to be given at BATIMAT on Wednesday 6 November from 10.30 to 11.15 in the ZOOM area, hall B of the Paris/Villepinte exhibition centre.

A large market in terms of both volume and value, technical textiles dedicated to the construction industry (civil engineering, public works and interior design) represent 12.7 billion dollars in the world's economy and 15% of all technical textiles; in Europe, technical textiles for the construction industry represent a volume of 5.9 thousand tonnes of materials. They are everywhere: in architectural structures, floor reinforcements, strengtheners, insulation materials, interior design and home automation. They are the materials of choice for their lightness, toughness, tensile properties and flexibility; textiles offer some essential advantages while meeting the highest standards and qualification levels.

Some major challenges to be met In years to come, there will be many challenges to be met regarding housing and infrastructures: the constant rise in population, concentrated in supercities in some emerging countries; the renewed appeal of the countryside in Europe's new "rurban" areas. We need to design compact, high rise towns to compensate for the shortage of land; design ecological, digital towns with autonomous energy supplies; create synergies between the town and the country, where nature rubs shoulders with technology; invent new places to live and share community life... There is no end to the possibilities for the future. Energy issues are also a major challenge: there are 30.7 million homes in France, representing 42.5% of our energy consumption and producing 23% of total greenhouse gas emissions (averaging 240 kWh/m²/year for older properties). For new housing and renovation projects, the efficiency level required by French "BBC" (bâtiments basse consommation or low consumption buildings) standards sets the maximum energy consumption at 50kWh/m²/year (weighted according to climate and altitude).

Viewpoints | Some big names have joined the CETI's Scientific Commitee.

Some big names have joined the CETI's Scientific Committee.

Eric Devaux, University Professor, has just taken over the position of Director of the Scientific Committee. He has brought together producers of raw materials such as Arkema and Solvay; end users such as EADS, Damart, Saint-Gobain and Macopharma; academic research with IFMAS (Institut Français des Matériaux Agro-sourcés), Materia Nova (expert centre dedicated to materials), Chimie Lille (ENSCL), ENSAIT/GEMTEX lab, Institut Chevreul and IEMN alongside competitive clusters I-Trans and UP-tex, with the support of CLUBTEX, Edana and the Nord-Pas-de-Calais region.

Samuel Solarski, Group Leader European Adfors Lab Coating and Composites Department, tells us about his experience.

What made Saint-Gobain Recherche join the scientific committee of CETI?Saint-Gobain Recherche is one of the seven main research centres for the Saint-Gobain group. The "European Adfors Lab" team which belongs to the Coating and Composites Department is currently developing new technical textiles. For this we need to put regular cooperation actions in place in order to conduct pilot tests on those technologies we do not have access to internally. CETI was for us an excellent tool for innovation for the use of firms.

What are you working on at the moment?We are working on various subjects: the development of new functionalized wall coverings (easy to install, with air purifying functions, acoustic properties, etc.), new biosourced binders, textiles from renewable resources, nonwovens for roofing applications.

You are leader of the Technical Textiles group (European Adfors Lab). What are your main challenges? Which markets are you targetting?After specializing in textiles for my PhD in engineering at ENSAIT, I have been working with my team to develop technical textiles for the domestic markets such as wall coverings, masts, webs and reinforcement mesh for bituminous flooring and roofing systems. We aim to provide additional functionalities to textiles (comfort, acoustic properties, fire-resistant properties), improve their reinforcing properties and use materials with lower environmental impacts.

Biosourced materials at CETI !

Achieving added value through the use of biosourced polymers in textiles applications is one of CETI's priorities.

To meet this goal, melt spinning tests have been conducted by Arkema. "These initial tests on the processability of our Rilsan PA11(r) on CETI's machines have been a total success" explains Jean-Jacques Flat, Compounding and Processing Department Manager of CERDATO.Used for over 60 years in extrusion and injection moulding as well as in melt spinning at the outset of its long career, PA11 is a synthetic polymer made from a natural material, castor oil. Its chemical resistance combined with excellent mechanical strength make it the ideal raw material for technical textiles.Our single-component tests on this material allowed us to study its behaviour during the spinning process and to optimise the extrusion temperature range. The resulting product was a 36 strand multifilament yarn with 2.1 dtex per strand.

PA11, PLA and other "green" polymers can look forward to other developments at CETI.

CETI's first steps have been giant ones !

Premiers pas réussis pour le CETI !

News | France-Japan, a working group that should enable CETI to develop its technological and commercial partnerships.

France-Japan, a working group that should enable CETI to develop its technological and commercial partnerships.

CETI The main aim was to work on raw materials. In the short term, the strategy is to consolidate relations between French SME and some major Japanese groups (the gateway to fibres for SME), and to attract investors in the longer term. Bertrand Delesalle, President of CETI, the European Centre for Innovative Textiles and the key project of the UP-tex cluster, and Stéphan Vérin, Operational Director of the UP-tex cluster consider that "France has the capacity to host Japanese research students and businesses who could conduct their development or prototyping work at CETI, the European Centre for Innovative Textiles, in order to step up academic research in conjunction with industrial projects". Kyoto University has also recently visited CETI and the region's facilities.
